In 1517 Adolf succeeded Philip of Burgundy-Blaton, who became Bishop of Utrecht, as admiral of the Netherlands until 1540.
As a result, he equipped some warships to protect the Dutch herring fishing fleet.
In 1525 he accompanied a delegation of the Emperor to England, where he helped to conclude a treaty with France, in which the herring fishing was declared free.
During his life, Adolf acquired great merits around the province of Zeeland, especially in building dikes and by his tireless support for trade, shipping and traffic.
On the other hand, he was a fervent supporter of the Catholic Church and therefore countered the Reformation with irreconcilable hate.
